Roofing Technology for Schools

Superior chemical resistance, where chemical exposure on the roof is of concern, such as chlorine, PVC is an excellent choice. Where interior humidity is a concern, the addition of a vapor retarder at the deck level will mitigate the condensation potential within the roof assembly.

Multi-layer asphalt systems will provide robustness and redundancy to protect the interior of the school. The addition of a DensDeck Storm X roof board can protect against the most severe hail storms, including Very Severe Hail. Where interior humidity is a concern, the addition of a vapor retarder at the deck level will mitigate the condensation potential within the roof assembly.

A best all-around roofing membrane option, TPO provides many installation options, including an adhered membrane option to reduce thermal bridging by conventional fasteners. The addition of an adhered HD polyiso cover board futher reduces thermal bridging and adds an R-value of 2.5 per half inch.

For a traditional steep-slope roof assembly, asphalt shingles provide excellent wind ratings. Combined with a GAF low-slope roof system, the entire roof can be covered under a warranty from a single- manufacturer.

Superior chemical resistance, where chemical exposure on the roof is of concern, such as from cooking oils and greases, PVC is an excellent choice. The factory applied fleece back enables PVC to be installed directly over an asphaltic membrane either in a new roof or as a recover to create a hybrid system.
